If you have Wi-Fi issues in Windows 11, you're not alone; Microsoft pulls problematic update
A number of Windows 11 users are reporting Wi-Fi connectivity issues after installing the December 2023 Patch Tuesday update. The KB5033375 cumulative update was released for Windows 11 versions 22H2 and 23H2, and the release was followed by complaints from users unable to connect to networks.
Microsoft has acknowledged the issue in relation to not only KB5033375, but also the earlier KB5032288 preview update. There is good news in that home users appear to be unaffected, but things are less rosy for enterprise and education users.
